This example shows how to listen to and handle some events on the map.

For more information, see the documentation.

Before you can try the sample code, you must configure your development environment. For more information, see Maps SDK for Android code samples.

    OnMapLongClickListener, OnCameraIdleListener, OnMapReadyCallback {

    private lateinit var tapTextView: TextView
    private lateinit var cameraTextView: TextView

        val mapFragment = supportFragmentManager.findFragmentById(R.id.map) as SupportMapFragment?
        mapFragment?.getMapAsync(this)
        applyInsets(findViewById<View?>(R.id.map_container))
    }

Git is required to run this sample locally. The following command clones the sample application repository.

git clone git@github.com:googlemaps-samples/android-samples.git

Import the sample project into Android Studio:

1. In Android Studio, select File > New > Import Project.

2. Go to the location where you saved the repository and select the project directory for Kotlin or Java:

   • Kotlin: PATH-REPO/android-samples/ApiDemos/kotlin
   • Java: PATH-REPO/android-samples/ApiDemos/java
3. Select Open. Android Studio builds your project, using the Gradle build tool.
4. Create a blank secrets.properties file in the same directory as your project's local.properties file. For more information about this file, see Add your API key to the project.
5. Get an API key from your project with the Maps SDK for Android enabled.

6. Add the following string to secrets.properties, replacing YOUR_API_KEY with the value of your API key:

   MAPS_API_KEY=YOUR_API_KEY

7. Run the app.
